What your IBM BladeCenter JS20 Type 8842 offers

Your blade server is designed to take advantage of advancements in memory management and data storage. Your blade server includes:

IBM PowerPC

IBM PowerPC 970 microarchitecture technology leverages proven innovative IBM technologies to build powerful, scalable, reliable IBM-processor-based servers. PowerPC 970 microarchitecture technology includes features such as light path diagnostics, Predictive Failure Analysis (PFA), and Advanced System Management.

Impressive performance using the latest microprocessor technology

Your blade server supports two IBM PowerPC 970 microprocessors and comes with two microprocessors installed. Together, these two microprocessors enhance performance. With two microprocessors, your blade server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. To use SMP, obtain an SMP-capable operating system. For a list of supported operating systems and other options, go to http://www.ibm.com/pc/us/compat/.

Integrated network environment support

Your blade server comes with one integrated dual-port Gigabit Ethernet controller. Each Ethernet controller port has an interface for connecting to 10/100/1000-Mbps networks through an Ethernet-compatible switch module on the BladeCenter unit. The blade server automatically selects between 10BASE-T and 100/1000BASE-TX environments. Each controller port provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data

the Ethernet local area network (LAN). The controller supports Wake on LAN

technology.

I/O expansion

Your blade server comes with two connectors on the system board for an optional I/O expansion card for adding more network communication capabilities

the blade server.

Large system memory

The memory bus in your blade server supports up to 4 GB of system memory. The memory controller provides support for up to four industry-standard 2.5 V, 184-pin, double-data-rate (DDR), PC2700, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) dual inline memory modules (DIMMs). For the most current list of supported DIMMs, see the ServerProven

Light path diagnostics

Light path diagnostics provides light-emitting diodes (LEDs) to assist in isolating problems with the blade server. An LED on the blade-server control panel is lit if

unusual condition or a problem occurs. If this happens, you can look at the LEDs on the system board to locate the source of the problem. For more information, see “Light path diagnostics overview” on page 92.

Serial Over LAN

Your blade server supports Serial Over LAN (SOL) technology, which provides advanced remote management capability. It provides the ability to redirect server serial data over a LAN without the use of serial concentrators. It also eliminates the need for serial cabling by internally rerouting serial packets over the LAN.

Chapter 2. Blade server power, controls, and indicators

This chapter describes the power features, how to turn on and turn off the blade server, and what the controls and indicators mean.

Turning on the blade server

Important: To generate faster blade-server startups from the network, connect the

dynamic host configuration protocol (DHCP) server to the Ethernet switch module in I/O bay 2 in the BladeCenter unit. The system firmware code in the blade server detects this Ethernet controller first. The Ethernet controller in each blade server is then associated with the switch module in I/O bay 2.

Notes:

After you connect the power cords of your BladeCenter unit to the electrical outlets, wait until the power-on LED on the blade server flashes slowly before pressing the blade server power-control button. Before the LED flashes, the service processor in the BladeCenter management module is initializing, and the power-control button on the blade server will not respond.

While the blade server is powering up, the power-on LED on the front of the server is lit. See “Blade server controls and LEDs” on page 15 for the power-on LED states.

After an orderly shutdown of the operating system occurs, the Wake on LAN feature is permanently enabled in the blade server system firmware code. Therefore, Enabled is the default setting. The Wake on LAN setting for each blade server is stored in the management-module nonvolatile random-access memory (NVRAM). To disable the Wake on LAN feature for one or more blade servers, use the BladeCenter management-module Web interface. For more information about the BladeCenter management-module Web interface, see the

BladeCenter Management Module User’s Guide on the IBM BladeCenter Documentation CD.

System reliability guidelines

help ensure proper cooling and system reliability, make sure that: The ventilation holes on the blade server are not blocked. Each of the blade bays on the front of the BladeCenter unit has a blade server or

filler blade installed. Do not operate the BladeCenter unit for more than 1 minute without a blade server or filler blade installed in each blade bay.

You have followed the reliability guidelines in the documentation that comes with the BladeCenter unit.

You have not installed any small computer system interface (SCSI) devices. The blade server does not support SCSI devices. If you attach SCSI devices to the blade server, these devices will not be recognized or configured, and they will not operate.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To

avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

reduce the possibility of electrostatic discharge, observe the following

precautions:

Limit your movement. Movement can cause static electricity to build up around you.

Handle the device carefully, holding it by its edges or its frame.

not touch solder joints, pins, or exposed printed circuitry.

not leave the device where others can handle and damage it.

While the device is still in its static-protective package, touch it to an unpainted metal part of the BladeCenter unit for at least 2 seconds. This drains static electricity from the package and from your body.

Remove the device from its package and install it directly into the blade server or BladeCenter unit without setting the device down. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device

your blade server cover or on a metal surface.

Installing memory modules

You can increase the amount of memory in your blade server by installing additional memory-module options. When you install memory, you must install a pair of matched dual inline memory modules (DIMMs).

Notes:

The system board contains four DIMM connectors and supports two-way memory interleaving.

The DIMM options available for your blade server are 256 MB, 512 MB, and 1 GB. Your blade server supports a minimum of 512 MB and a maximum of 4 GB

system memory.

Both DIMMs in a pair must be the same size, speed, type, and technology. You can mix compatible DIMMs from various manufacturers.

The second pair of DIMMs does not have to be the same size, speed, type, and technology as the first pair.

The blade server does not support unregistered DIMMs. Install only 2.5 V, 184-pin, double-data-rate (DDR), PC2700, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest PC2700 SDRAM Registered DIMM specification, which is available from http://www.jedec.org/. For a list of supported options for your blade server, go to http://www.ibm.com/pc/us/compat/.

PC2700 DIMMs are compatible with earlier specifications and work in the PC2100 and PC1600 DIMM connectors.

Installing or removing DIMMs changes the configuration information for the blade server. After you install or remove a DIMM, the new configuration information is automatically saved in the blade server firmware code. You can verify the latest configuration information by viewing the blade server firmware code as described

Installing an I/O expansion card

You can add an optional I/O expansion card (adapter) to your blade server to give the blade server additional network connections for communicating on a network.

When you add an I/O expansion card, you must make sure that the switch modules

I/O bays 3 and 4 on the BladeCenter unit both support the I/O expansion card network-interface type. For example, if you add an Ethernet expansion card to your blade server, the modules in I/O bays 3 and 4 on the BladeCenter unit must both

compatible with the Ethernet expansion card. All other I/O expansion cards installed on other blade servers in the BladeCenter unit must also be compatible with these switch modules. In this example, you could then install two Ethernet switch modules, two pass-thru modules, or one Ethernet switch module and one pass-thru module. Because pass-thru modules are compatible with a variety of I/O expansion cards, installing two pass-thru modules would allow use of several different types of compatible I/O expansion cards within the same BladeCenter unit.

Important:

Installation of an I/O expansion card requires removal of the hard disk drive that

installed in IDE connector 2. The I/O expansion card occupies the same space

this hard disk drive and replaces it. You cannot install a hard disk drive in IDE

connector 2 while an I/O expansion card is installed in the blade server. When you install a Myrinet Cluster Expansion Card for IBM Eserver

BladeCenter into a BladeCenter JS20 Type 8842, you must connect the cable from the I/O expansion card to the J7 connector on the system board.

Attention: If the hard disk drive installed in IDE connector 2 contains any

information that you want to keep, back it up to another storage device.

The following illustration shows how to install an I/O expansion card on the blade server. The card is installed near IDE connector 2.

Installing an Ethernet cable

One dual-port Gigabit Ethernet controller is integrated on the BladeCenter JS20 Type 8842 system board. To support Ethernet connections and the SOL feature and

configure your blade server, you must install an optional Ethernet-compatible

switch module, such as the Nortel Networks Layer 2-7 GbE Switch Module for IBM

Eserver BladeCenter or IBM 4-Port Gb Ethernet Switch Module for BladeCenter,

I/O bay 1 of the BladeCenter unit.

you plan to use both Ethernet controller ports, you must install an identical Ethernet switch module in I/O bays 1 and 2, since both I/O bays require the same type of optional Ethernet-compatible switch module. Each controller port provides a 1000-Mbps full-duplex interface for connecting to one of the Ethernet-compatible switch modules in I/O bays 1 and 2. If you plan to attach additional Ethernet devices to the blade server or the BladeCenter unit, you must install an optional Ethernet-compatible switch module, such as the Nortel Networks Layer 2-7 GbE Switch Module for IBM Eserver BladeCenter or IBM 4-Port Gb Ethernet Switch Module for BladeCenter, in I/O bay 3 or 4 of the BladeCenter unit, to support these

Chapter 4. Installing and removing options and customer-replaceable units

additional Ethernet connections. If you install optional Ethernet-compatible switch modules in I/O bays 3 and 4, these switch modules must be identical.

The optional Ethernet switch modules contain four ports with RJ-45 connectors. These connectors provide a 10/100/1000 Base-T interface (either at half-duplex or full duplex) for connecting twisted-pair cable to the Ethernet network. You must purchase and install a compatible cable to connect these devices. To connect an Ethernet controller port to a repeater or switch module, use an unshielded twisted pair (UTP) cable with RJ-45 connectors at both ends. For 100 Mbps or higher operation, Category 5 cabling is required. For 10 Mbps operation, Category 3 cabling is required.

Notes:

The BladeCenter unit contains the input/output connectors that are available to your blade server. See the documentation that comes with your BladeCenter unit for information about the input/output connectors.

The blade server does not support a direct connection to a monitor, keyboard, or mouse. Therefore, to enable communication between the blade server and these devices, you must establish an SOL connection and perform the configuration tasks that are described in Chapter 5, “Configuring your blade server,” on page 41. In addition, you must start an SOL session as described in Chapter 6, “Running a Serial Over LAN session,” on page 57.

Chapter 4. Installing and removing options and customer-replaceable units

BladeCenter JS20 Type 8842: Installation and User’s Guide

Chapter 5. Configuring your blade server

This chapter contains instructions for establishing a Serial Over LAN (SOL) connection, enabling the SOL feature, and configuring the blade server so that you can run SOL sessions and use the BladeCenter management-module command-line interface. This chapter also explains how to update and configure BladeCenter components for SOL operation using the management-module Web-based management and configuration program. The IBM Eserver BladeCenter management-module command-line interface provides access to the text-console command prompt on each blade server through an SOL connection, enabling the blade servers to be managed from a remote location.

You also can perform many configuration procedures using the management-module command-line interface. See the IBM Eserver BladeCenter

Management Module Command-Line Interface Reference Guide on the IBM BladeCenter Documentation CD for information and instructions. In addition, you

can use the simple network management protocol (SNMP) to perform configuration procedures. SNMP commands are described in the IBM Eserver BladeCenter

Management Module Command-Line Interface Reference Guide on the IBM BladeCenter Documentation CD. For additional information about SNMP, see also

the IBM 4-Port Gb Ethernet Switch Module for BladeCenter Installation and User’s

Guide or Nortel Networks Layer 2-7 GbE Switch Module for IBM BladeCenter Installation Guide on the IBM BladeCenter Documentation CD.

The firmware code in your blade server uses auto-configuration; therefore, additional blade-server configuration programs are not required for the blade server. However, if you have attached other devices to the blade server or the BladeCenter unit, you must configure those devices as described in the applicable documentation that comes with those devices or the BladeCenter unit. You do not have to set any passwords to use the blade server. If you change the battery or replace the system board, you must reset the date and time through your operating system.

For information about setting up your network configuration for remote management, see the IBM Eserver BladeCenter Planning and Installation Guide. You can obtain the planning guide from the Web site at http://www.ibm.com/pc/eserver/bladecenter.

Note: Before you can run programs on the blade server, you must establish an

SOL connection and install an operating system on the blade server. For information about installing your operating system, see Chapter 7, “Installing the operating system,” on page 61.

Using the Serial Over LAN (SOL) feature on the blade server

Before you can perform the following tasks, you must establish an SOL connection and start an SOL session on the blade server:

Establishing a communications channel between the blade server and a compatible monitor (or video console), keyboard, and mouse.

Installing the operating system on the blade server. Configuring the SOL feature. Running diagnostics programs. Having the blade server serviced.

To support the SOL feature and to configure your blade server, you must install a compatible Ethernet switch module in I/O bay 1 of the BladeCenter unit. Examples

compatible Ethernet switch modules are the IBM 4-Port Gb Ethernet Switch Module for BladeCenter and the Nortel Networks Layer 2-7 GbE Switch Module for IBM BladeCenter. For more information about these switch modules, see the IBM

4-Port Gb Ethernet Switch Module for BladeCenter Installation and User’s Guide or Nortel Networks Layer 2-7 GbE Switch Module for IBM BladeCenter Installation Guide on the IBM BladeCenter Documentation CD. For more details, see the

following information:

Chapter 6, “Running a Serial Over LAN session,” on page 57.

The IBM Eserver BladeCenter Management Module Command Line Interface

Reference Guide on the IBM BladeCenter Documentation CD.

Note:

The BladeCenter unit supports up to four Ethernet switch modules.

The SOL feature is accessed through the management-module command-line interface. For information about using the command-line interface, see “Using the command-line interface” on page 56 and the IBM Eserver BladeCenter

Management Module Command Line Interface Reference Guide on the IBM BladeCenter Documentation CD.

Configuring the BladeCenter unit for the Serial Over LAN (SOL) feature

This section provides instructions for configuring the BladeCenter unit to operate using SOL. The BladeCenter unit needs to be configured only once. The settings in this section are used by all components in the BladeCenter unit. See “Configuring the BladeCenter components for Serial Over LAN operation” on page 46 for SOL configuration steps that are specific to each BladeCenter component.

SOL configuration that is shared by all BladeCenter components is performed using the management-module Web-based user interface. The management-module Web-based user interface supports only configuration and monitoring of the command-line interface and SOL and cannot be used to start command-line interface or SOL sessions.

Note: Throughout this document, the management-module Web-based user

interface is also known as the BladeCenter management-module Web interface.

Some SOL configuration can also be performed using the management-module command-line interface. See the IBM Eserver BladeCenter Management Module

Command-Line Interface Reference Guide on the IBM BladeCenter Documentation

for information and instructions.

After you install the operating system (including the Ethernet device drivers) on your blade server, you can use either Telnet or Secure Shell (SSH) sessions to communicate with the blade server. An SOL session must be used for the initial installation of the operating system.

Before you continue with the configuration tasks, read the information in “Preinstallation requirements” on page 11.

Configuring the Gigabit Ethernet controller

One dual-port Gigabit Ethernet controller is integrated on the blade server system board. Each controller port provides a 1000-Mbps full-duplex interface for connecting to one of the Ethernet-compatible switch modules in I/O bays 1 and 2, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). Each Ethernet-controller port on the system board is routed to a different switch module in I/O bay 1 or bay 2. The routing from the Ethernet-controller port to the I/O bay will vary according to whether an Ethernet adapter is enabled and the operating system that is installed. See “Blade server Ethernet controller enumeration” for information about how to determine the routing from the Ethernet-controller ports to I/O bays for your blade server.

Note: Other types of blade servers, such as the BladeCenter HS20 Type 8678, that

are installed in the same BladeCenter unit as this BladeCenter JS20 Type 8842 might have different requirements for Ethernet controller routing. See the documentation that comes with the other blade servers for detailed information.

You do not have to set any jumpers or configure the controllers for the blade server operating system. However, you must install a device driver to enable the blade server operating system to address the Ethernet-controller ports. For device drivers and information about configuring your Ethernet-controller ports, see the Ethernet software documentation that comes with your blade server, or contact your IBM marketing representative or authorized reseller. For updated information about configuring the controllers, go to the IBM Support Web site at http://www.ibm.com/pc/support/.

Blade server Ethernet controller enumeration

The enumeration of the Ethernet controllers or controller ports in a blade server is operating-system dependent. You can verify the Ethernet controller or controller port designations that a blade server uses through your operating-system settings.

The routing of an Ethernet controller or controller port to a particular BladeCenter unit I/O bay depends on the type of Ethernet expansion card that is installed. You can verify which Ethernet-controller port in this blade server is routed to which I/O bay by using the following test:

Install only one Ethernet switch module or pass-thru module, in I/O bay 1. Make sure that the ports on the switch module or pass-thru module are enabled

(Switch Tasks → Management → Advanced Switch Management in the BladeCenter management-module Web interface).

Enable only one of the Ethernet-controller ports on the blade server. Note the designation that the blade server operating system has for the controller port.

Ping an external computer on the network connected to the Ethernet switch module. If you can ping the external computer, the Ethernet-controller port that you enabled is associated with the switch module in I/O bay 1. The other Ethernet-controller port in the blade server is associated with the switch module

I/O bay 2.

Communications from optional Ethernet adapters and other I/O expansion cards are routed to I/O bays 3 and 4. You can verify which controller port on an expansion card is routed to which I/O bay by performing the same test, using a controller on the expansion card and a compatible switch module or pass-thru module in I/O bay

Updating the firmware code for your blade server and the service processor

Your blade server contains firmware code. In addition, the service processor in your blade server comes with its own firmware code. IBM will periodically make firmware updates available for your blade server and the service processor. You can maintain the latest levels of firmware code for your blade server and the service processor in your blade server by installing firmware updates as they become available. Be sure

follow the instructions in this section.

Complete the following steps to view the current firmware code levels for your blade server and the service processor:

Access and log onto the BladeCenter management-module Web interface as described in the IBM Eserver BladeCenter Type 8677 Installation and User’s

Guide on the IBM BladeCenter Documentation CD.

From the Blade Tasks section, select Firmware VPD.

The Blade Server Firmware VPD window contains the build identifier, release, and revision. Compare this information to the firmware information on the IBM Support Web site at http://www.ibm.com/pc/support/. If these two types of information match, then your blade server has the latest firmware code. If these two types of information differ, download the latest firmware code from the IBM Support Web site. Follow the update instructions on the IBM Support Web site.

apply the latest firmware code for your blade server service processor, flash the service processor. Download the latest firmware code for your blade server service processor from the IBM Support Web site at http://www.ibm.com/pc/support/. Use the BladeCenter management-module Web interface to flash the service processor. Follow the update instructions on the IBM Support Web site.

Important: To avoid problems and to maintain proper system performance, always

make sure that the blade server firmware code, service processor code, and diagnostic firmware code levels are consistent for all blade servers within the BladeCenter unit.

Chapter 6. Running a Serial Over LAN session

The IBM Eserver BladeCenter management-module command-line interface provides a convenient method for entering commands that manage and monitor BladeCenter components. The blade server does not support a direct connection to

monitor, keyboard, or mouse. Therefore, to enable communication between the blade server and these devices, you must first configure the SOL feature on the blade server to establish an SOL connection as described in Chapter 5, “Configuring your blade server,” on page 41 and then start an SOL session as described in this chapter.

This chapter contains the following information about running an SOL session:

Starting the command-line interface Establishing a Telnet connection Establishing a Secure Shell (SSH) connection Starting an SOL session Ending an SOL session

the BladeCenter environment, the integrated system management processor (ISMP) and network interface card (NIC) on each blade server route the serial data from the blade server serial communications port to the network infrastructure of the BladeCenter unit, including an Ethernet compatible I/O module that supports SOL communication. Configuration of BladeCenter components for SOL operation is done through the BladeCenter management module (see Chapter 5, “Configuring your blade server,” on page 41). The management module also acts as a proxy in the network infrastructure to couple a client running a Telnet session with the management module to an SOL session running on a blade server, enabling the Telnet client to interact with the serial port of the blade server over the network. Because all SOL traffic is controlled by and routed through the management module, administrators can segregate the management traffic for the BladeCenter unit from the data traffic of the blade servers.

start an SOL connection with a blade server, you must first start a Telnet command-line interface session with the management module. When this Telnet command-line interface session is running, you can start a remote console SOL session with any blade server in the BladeCenter unit that is set up and enabled for SOL operation. You can have as many as 14 simultaneous SOL sessions active (one for each of up to 14 blade servers) with six additional command-line interface sessions available for BladeCenter unit management. If security is a concern, you can use SSH sessions to establish secure Telnet command-line interface sessions with the BladeCenter management module before starting an SOL console redirect session with a blade server.

BladeCenter Management Module Command Line Interface Reference Guide for

information about:

Command-line interface guidelines Command syntax and descriptions Command-line interface error messages

Selecting the command target

You can use the command-line interface to target commands to the management module or to other devices installed in the BladeCenter unit. The command-line prompt indicates the persistent command environment: the environment where commands are entered unless otherwise redirected. When a command-line interface session is started, the persistent command environment is “system”; this indicates that commands are being directed to the BladeCenter unit. See the IBM

Eserver BladeCenter Management Module Command Line Interface Reference

Guide for additional information.

Starting the command-line interface

Start the management-module command-line interface from a client computer by establishing a Telnet connection to the IP address of the management module or by establishing an SSH connection. You can establish up to 14 separate Telnet or SSH sessions to the BladeCenter management module.

Although a remote network administrator can access the management-module command-line interface through Telnet, this method does not provide a secure connection. As a secure alternative to using Telnet to access the command-line interface, SSH ensures that all data that is sent over the network is encrypted and secure.

The following SSH clients are available. Although some SSH clients have been tested, support or nonsupport of any particular SSH client is not implied.

The SSH clients distributed with operating systems such as SUSE LINUX, Red Hat Linux, AIX®, and UNIX information). The SSH client of Red Hat Linux 8.0 Professional was used to test the command-line interface.

The SSH client of cygwin (see http://www.cygwin.com for information) Putty (see http://www.chiark.greenend.org.uk/~sgatham/putty/ for information)

Chapter 7. Installing the operating system

Important:

Before you install the operating system on the blade server, make sure that you provide an SOL connection between the blade server and a compatible monitor (or video console), keyboard, and mouse. You must do this because the blade server does not support a direct connection to these devices. The SOL connection serves as a communications channel between the blade server and these devices. The SOL feature must be enabled for both the BladeCenter unit and the blade server before you can start an SOL session with the blade server. Therefore, do not disable this feature. If you have not already done so, you must configure the SOL feature on the blade server to establish an SOL connection and enable the SOL feature as described in Chapter 5, “Configuring your blade server,” on page 41 and start an SOL session as described in Chapter 6, “Running a Serial Over LAN session,” on page 57.

See the IBM Eserver BladeCenter Management Module Command Line

Interface Reference Guide for information about SOL commands. See your

operating-system documentation for information about SOL commands that you can enter using the command-line interface.

you plan to install the operating system through the Ethernet network, you must install a second Ethernet switch module into I/O bay 2 of the BladeCenter unit. For additional information, see Chapter 5, “Configuring your blade server,” on page 41.

Note: This Ethernet switch module must be of the same type that you installed

I/O bay 1 of the BladeCenter unit.

After you install the operating system on your blade server, you must install any service packs or update packages that come with the operating system. For additional information, see the instructions that come with your operating-system documentation and the service packs or update packages.

The BladeCenter JS20 Type 8842 has no external USB ports; however, it can communicate with and use the USB diskette drive and CD-ROM drive that are in the BladeCenter unit chassis.

Due to SOL requirements, you must select or install network device drivers after you install the operating system. This includes the BladeCenter JS20 Type 8842 Broadcom Ethernet controller device driver (for additional information, see the instructions that come with the device driver).

Chapter 8. Solving problems

This section provides basic troubleshooting information to help you solve some common problems that might occur while setting up your blade server.

you cannot locate and correct the problem using the information in this section,

see the BladeCenter JS20 Type 8842 Hardware Maintenance Manual and

Troubleshooting Guide on the IBM BladeCenter Documentation CD that comes with

your BladeCenter unit, and the Server Support flowchart in the front of this book.

Diagnostic tools overview

The following tools are available to help you identify and solve hardware-related problems:

Diagnostic programs, firmware error codes, and location codes

The system diagnostic programs are provided in read-only memory (ROM). These programs test the major components of your blade server. For detailed descriptions of the firmware error codes, see “Firmware error codes” on page 80.

Some firmware error codes also include location codes. The location code information is required to identify the failing component. Check the system error logs and event logs to determine the location code information that corresponds

the firmware error code. Troubleshooting charts These charts list problem symptoms and steps to correct the problems. See the

“Troubleshooting charts” on page 89 for more information. Light path diagnostics Use light path diagnostics to diagnose system errors. See “Light path diagnostics

overview” on page 92 for more information. Power-on self-test (POST) firmware checkpoints and error codes. See

“Checkpoint codes” on page 64 for more information. The firmware checkpoints are progress codes that your blade server displays

during the power-on self-test (POST).
